Staking is a process in the world of cryptocurrencies where individuals lock up their coins to support the operations of a blockchain network. By doing this, they help validate transactions and secure the network. In return for their contribution, stakers can earn rewards, often in the form of additional coins. This method is commonly used in Proof of Stake (PoS) systems, which are alternatives to the traditional Proof of Work (PoW) systems. Staking can be seen as a way to earn passive income while also participating in the growth and stability of a cryptocurrency network.
